Hybrids affect vegetative development in silage corn and forage sorghum. Investigations were conducted on the hybrid selection and impact on vegetative development for multiple irrigation treatments in Jordan. The study was carried out under the Norman Borlaug Fellowship during the 2017 season which demonstrated a suitable selection for forage growers. The first step required the selection of drought-tolerant hybrids. Five commercial seed lots (three of corn and two of sorghum) were tested. The second step involved planting hybrids under field conditions at Florida Agricultural and Mechanical University using a designed irrigation treatment and then evaluating the vegetative growth and development by measuring emergence rate index, seedling dry weight, tissue water content percentage, total leaf count, plant height, and fodder yield of the first harvest. Silage corn (6640VT3P) seed had lower water uptake and higher seedling dry weight aligned with a suitable seedling tissue water content and fodder yield of the first harvest. The superiority of silage corn (6640VT3P) may be attributed to hybrid vigor and its efficient water usage habit. These findings suggest that silage corn (6640VT3P) had a high impact on the vegetative development that could be selected and grown using irrigation treatment under extreme drought conditions identical to Jordan.
